This invention relates to tool attachments and more particularly to anattachment carried on the shank of the tool and shiitable into and/orout of working position.

One of the prime objects of the invention is to provide a toolattachment, such attachments being in the form of punches, chisels,screw driver blades, and similar attachments which can be quickly andeasily shifted into or out of working position, obviating the necessityof having complete and individual tools of all kinds, the blade of thetool on which the at- -tachment is mounted serving as a support on whichthe various attachments are mounted.

Another object is to design an attachment which is readily attachable ordetachable, and in which the attachment blade snaps into or out ofworking position.

A further object is to provide an attachment which can be mounted on ascrew driver or similar tool, and which can be racked into or out ofposition, obviating the necessity oftwo separate individual tools, sothat the workman, when working on a ladder, scaifold, or other support,requires but one hand to manipulate two tools, thusmaking for safety,quicker work, and easy operation.

A further" object still is to design an attachment which can be readilymanufactured and assembled, which has a'wide range of adjustability tosuit screw driver or tools of various sizes, and which is readilyremovable as a unit when desired.

With the above and other objects in view, the present invention consistsin the combination and arrangement of parts, hereinafter more fullydescribed, illustrated in the accompanying drawin in the appendedclaims, it being understood that changes may be made in the form, size,proportion, and minor details of construction, without departing fromthe spirit, or sacrificing any of the advantages of the invention.

In the drawing 1 is a view of a conventional screw driver, showing oneof my attachments mounted thereon.

Fig. 2 is an edge View, the broken lines showing the'attachment inadjusted position on the shank, the tool proper being .folded on theholder.

Fig. 3 is a rear view.

,Fig. 4 is a detail vertical sectional view of the holder.

and particularly pointed out I then swung downwardly by racking Fig. 5is a transverse sectional view through the holder.

Fig. 6 is an edge view of the tool mounting.

Referring now more specifically to the drawing, the numeral 8 indicatesthe shank of a conventional screw driver which is provided with a handle9 as usual, the end of the blade it] of the screw driver being wedgeshaped in the conventional manner.

A holder H is adjustably mounted on the blade! and is preferably formedof rubber, so that it frictionally engages the shank of the screw driverand remains in adjusted position, this holder being substantiallyegg-shaped,

and a centrally disposed opening I2 is provided therethrough, the endsections only of said opening engaging the screw so that the holder maybe moved and adjusted without excessive friction.

Spaced apart, horizontally disposed ribs l3 are provided on the outersurface of the holder and form a groove It in' which a tempered toolmounting or clip I5 is mounted, this clip being preferably formed ofwire, the ends being turned downwardly and terminating in eyes IE towhich the tool is attached. 0

In the present instanc I have shown this attachment in th form of asmall blade I'I, although it will be obvious that it can be a punch,awl, chisel, or other tool; this blade is formed as clearly shown inFigs. 1, 2, and 3 of the drawing; having a groove i8 adapted to receiveand accommodate the blade of the screw driver, the upper end terminatingin spaced apart legs l9, having inwardly projecting lugs 2% adapted forengagement by the eyes of the clip it.

The clip member is formed of resilient material, and the eyes,are sprungtowards each other so that the tool cannot become disengaged, and whenthe attachment is not in use, the blade H is swung upwardly and againstthe body of the holder, the shape and resiliency of the clip i5 holdingit in this position; and when it is desired to use the attachment, theholder H is forced downwardly to position as shown in solid lines inFig. 2. The attachment i1 is it over a piece of wood or any suitableprojection, the blade H) is then seated in the groove l8 which islocated intermediate the length of the holder it, and the attachment canthen be manipulated in exactly the same manner as if it had the usualbody and handle. It is out of the way driver shank or blade when not inuse, and requires but an instant to adjust. L

The attachment idea is particularly advantageous from the standpoint ofcost, -the workman need not carry a number of the conventional bulkytoolsythe adjustments are readily made and with one hand, leaving theother hand free for holding on, placing screws, or any other purpose.

From the foregoing description it will be obvious that I have perfecteda very simple, practical, and inexpensive attachment for screw driversand the like. i

What I claim is:

1. An attachment of the class described, and comprising a holder formedof resilient material having a centrally disposed passage therein, aresilient clip mounted on said holder and formed with eyes in the endsthereof, and an attachment hingedly connected to said eyes andadjustable to foldable or extendable position.

2. In an attachment of the character described, the combination of atool, a resilient holder adjustably mounted on said tool, an attachmenthingedly mounted on the holder, and means formed on said attachmentintermediate the length thereof for engagement with the blade of thetool to form an extension thereof. 5

3. In an attachment of the character described, the combination of atool,- a resilient holder adjustably mounted on the tool, a clip mountedon said holder, an attachment hingedly connected to the clip andadjustable to 10 folded or extended position, and a groove in saidattachment for engagement by the blade of the tool. o 4. In anattachment of the character described, the combination of a tool, aholder ver- 15 tically adjustable on the tool, an attachment hingedlymounted on the holder and adjustable to folded or extended position, anda blade a groove provided in said attachment for engagement with the endof the blade of the tool 20 when said attachment is in its extendedposition.
